The terms Deep Web, Deep Net, Invisible Web, or Dark Web refer to the content on the World Wide Web that is not indexed by standard search engines. The deepest layers of the Deep Web, a segment known as the Dark Web, contain content that has been intentionally concealed including illegal and anti-social information. The conventional Surface Web was discovered to be too risky for anonymity-seeking terrorists: they could be monitored, traced, and found. In contrast, on the Dark Web, decentralized and anonymous networks aid in evading arrest and the closure of these terrorist platforms. This paper reports some of the recent trends in terrorist use of the Dark Web for communication, fundraising, storing information and online material.

On this week’s blog, Professor Gabriel Weimann discusses his new book, published this month, From Theatres to Cyberspace: The Media and Terrorism which examines changing arenas of terrorist communication with a particular focus on emerging trends in the use of social media.

The Internet and online platforms have become a useful instrument for modern terrorists’ recruitment. Numerous studies explored the online recruitment of Jihadi groups and especially of the Islamic State (ISIS) that managed to recruit over 40,000 fighters from as many as 90 countries. Yet, these studies, focusing mainly on the online platforms and the appeals used, lacked a theoretical framework that can serve the search for the factors explaining process and its success. In this chapter we suggest that the notion of motivational imbalance as a key persuasive appeal in terrorist online recruitment can provide the needed psychological theoretical concept to explain their recruitment strategy. To do so, we examine terrorist online recruitment and its features (stages, type of messages, content of the messages, characteristics of the targets) and relate it to the notion of motivational imbalance. Then we explore the trend of ‘narrowcasting’ (focusing persuasive communication on selected target audiences) and how well it combines with motivational imbalance in the process of recruitment by terrorist groups. Finally, we demonstrate how motivational imbalance has been used in recent Jihadi recruitment campaigns. The evidence presented comes from the contents of recruitment campaigns as well as from the testimonies of recruits.

Bereits seit den 1990er Jahren gebrauchen TerroristInnen das Internet für ihre Zwecke, das ihnen ganz neue Möglichkeiten für Propaganda, Rekrutierung, Radikalisierung, Finanzierung und Planung eröffnet hat. Statt auf eigene Webseiten setzen TerroristInnen heute zunehmend und gezielt auf die Neuen Medien. Diese bieten eine hervorragende kostenlose Infrastruktur und erlauben es, ein globales Publikum zu erreichen. Dieser Beitrag beschreibt die terroristische Nutzung der drei größten Social Media-Dienste – Facebook, Twitter und YouTube – und das dahinterstehende Kalkül. Besondere Beachtung finden dabei Inhalte mit Bezug zu Deutschland.

Founded in 1996, the International Institute for Counter-Terrorism (ICT) is one of the leading academic institutes for counter-terrorism in the world, facilitating international cooperation in the global struggle against terrorism. ICT is an independent think tank providing expertise in terrorism, counter-terrorism, homeland security, threat vulnerability and risk assessment, intelligence analysis and national security and defense policy. ICT is a non-profit organization located at the Interdisciplinary Center (IDC), Herzliya, Israel which relies exclusively on private donations and revenue from events, projects and program.

The growing presence of modern terrorism on the Internet is at the nexus of two key trends: the democratization of communications driven by user-generated content on the Internet; and the growing awareness of modern terrorists of the potential of the Internet for their purposes. How best can the terrorists’ use and abuse of the Internet be countered? As this article argues, the answer to violent radicalization on the Internet lies not in censorship of the Internet, but in a more sophisticated and complicated strategy, relying on the theoretical notion of “noise” in communication process theory.
